Hodgkin's and non-Hodgkin's hepatic lymphoma: sonographic findings.

The sonographic studies of 72 patients with pathologically proven Hodgkin's or non-Hodgkin's hepatic lymphoma were retrospectively reviewed. Sixty-eight patients (94%) had secondary hepatic lymphoma (nine of them had AIDS-related lymphoma) and four patients (6%) had primary lymphoma of the liver. Forty-six of 72 patients (64%) had diffuse hepatic involvement, and 26 of 72 patients (36%) had focal liver lesions as demonstrated by sonography.

[Nonresectable fibrolamellar hepatocellular carcinoma: outcome of 4 cases treated by intra-arterial chemotherapy].

We evaluated the role of locoregional intraarterial treatment in the management of non-resectable fibrolamellar hepatocellular carcinomas (FLHCC) in 4 women. Three patients underwent transcatheter oily chemoembolization (TOCE) (7 courses), and one received intraarterial iodized oil with chemotherapeutic drug after surgical intraarterial catheter placement (1 course). The latter procedure resulted in marked discomfort and was therefore not repeated.

Preoperative assessment of resectability of hepatic metastases from colonic carcinoma: CT portography vs sonography and dynamic CT.

Objective: A retrospective study was performed to determine the influence of CT portography vs sonography and dynamic CT on the preoperative assessment of the resectability of hepatic metastases from colorectal cancer.

Materials And Methods: Results of sonography, bolus dynamic CT, and CT portography in 28 patients who underwent surgical exploration (resection or intraarterial catheter placement) for hepatic metastases from colorectal cancer were retrospectively reviewed by two abdominal radiologists and one hepatic surgeon. For each patient, the resectability and surgical approach were decided on the basis of the results of combined sonography-bolus dynamic CT and compared with the decision made from the CT portographic results alone.

[Anguilluliasis of the small intestine and AIDS. A case and review of the literature].

The authors report about one patient with an Acquired Immune Deficiency Syndrome (AIDS) presenting with strongyloidiasis involving the small bowel. On the basis of this observation, they describe the appearances of small bowel involvement by strongyloidiasis in patients with AIDS. They emphasize the main features differentiating these cases from the usual affection, namely the severity and diffusion of the lesions, as well as the presence of a very extensive associated lymphoid nodular hyperplasia.

Hepatic metastases from colorectal cancer: influence of hepatic volumetric analysis on surgical decision making.

A prospective study was performed to determine the impact of preoperative assessment of estimated postoperative liver volume on surgical decision making for liver metastases from colorectal cancer. Assessment of estimated postoperative liver volume was performed before surgery in 25 patients. Mean estimated postoperative liver volume +/- standard deviation (SD) was 697 cm3 +/- 317 (range, 320-1,532 cm3).

Comparative randomized double-blind study of hydroxyzine versus placebo as premedication before injection of iodinated contrast media.

The use of ionic contrast media in radiologic examinations may cause a wide variety of anaphylactoid reactions. The aim of this double-blind randomized study was to determine whether a simple and inexpensive premedication based on an antihistamine could reduce the number of idiosyncratic reactions in 400 patients (251 men and 149 women) without a clinical history of allergy who were to receive an intravenous injection of a low-osmolality iodinated contrast medium. Twelve hours before examination, a group of 200 patients was given one 100-mg tablet of hydroxyzine; another group of 200 was given a placebo tablet under the same conditions.

Detection of liver metastases from colorectal cancer: comparison of intraoperative US and CT during arterial portography.

A prospective study was performed to compare the sensitivities of intraoperative ultrasound (US) and computed tomography during arterial portography (CTAP) in the depiction of hepatic metastases from colorectal cancer. Twenty-five patients with hepatic metastases from colorectal cancer were evaluated. All patients underwent partial hepatectomy, and 56 metastases were pathologically proved.

[Magnetic resonance imaging of malignant hepatic tumors in adults].

Recently, magnetic resonance imaging (MRI) had an important place in imaging techniques of malignant primitive tumors of the liver. For many authors, this technique appears as the reference modality for hepatic tumor evaluation. Nevertheless, MRI is considered to be primarily a problem-solving rather than a screening modality.

[Amebic abscess of the caudate lobe. An uncommon topographic form].

Amebic liver abscess is the most common extraintestinal complication of invasive amebiasis. Amebic abscess is most often located in the right lobe of the liver which is affected four times as often as the left lobe. Location in the caudate lobe is exceptional.

Percutaneous ethanol injection for the treatment of symptomatic cystic metastases from ovarian carcinoma. Work in progress.

Two patients with symptomatic cystic metastases from ovarian epithelial carcinoma underwent ultrasound (US)-guided percutaneous aspiration and temporary injection of 99% ethanol into the cyst. In the first case, the patient initially underwent surgical resection of the mass and received systemic chemotherapy, but the cyst recurred 2 months later. Percutaneous aspiration and ethanol sclerotherapy were performed twice in the second case; fluid reaccumulated 2 months after the initial procedure.

Preoperative segmental localization of hepatic metastases: utility of three-dimensional CT during arterial portography.

To evaluate the accuracy of a fast three-dimensional (3D) reconstruction technique in determining the segmental location of hepatic metastases, 14 patients (40 metastases) were prospectively investigated before surgery with dynamic two-dimensional (2D) computed tomography during sequential arterial portography (CTAP). All patients underwent subsequent hepatic tumor resection within 4 days. After computer-generated mapping of hepatic venous structures with high attenuation and metastases with low attenuation, 3D reconstruction was performed.

CT of fibrolamellar hepatocellular carcinoma.

We retrospectively evaluated 10 patients with pathologically proven fibrolamellar hepatocellular carcinoma (FLHCC) to assess the utility of CT (n = 9), ultrasound (n = 10), angiography (n = 9), and MR (n = 3). The tumors were solitary in 6 of 10 patients, well delineated in 7 of 10, and hypervascular in 8 of 10. With use of multimodality imaging techniques, a central scar was demonstrated in 3 of 10 patients, calcifications in 4 of 10, dilated intrahepatic ducts in 2 of 10, thrombosis of a segmental portal branch in 2 of 10, and lymph node involvement in 3 of 10.

[Hemoperitoneum caused spontaneous rupture of hepatocellular carcinoma. Role of hepatic artery embolization in the therapeutic procedure].

A 73-year-old man with intraperitoneal haemorrhage due to spontaneous rupture of hepatocellular carcinoma was successfully treated by emergency transcatheter hepatic artery embolization. A safe hepatic resection was performed 30 days after the procedure. The patient was still alive four months after surgery.

[Evaluation of the role of MRI at 1.5 T in the staging of the initial extension of cancer of the uterine cervix].

To evaluate the sensibility and specificity of MRI in the initial staging of carcinoma of the uterine cervix, a retrospective study of 41 patients (48 MR scans) was undertaken. The sensitivity of T2-weighted images in the detection and determination of tumor location was 90% and specificity was 100%. On T2-weighted images, the signal intensity of the tumor was high in 64%.

Primary carcinoid tumor of the seminal vesicles: CT and MR findings.

A case of primary carcinoid tumor of the seminal vesicles is presented. To our knowledge, this case documented by CT and MRI is unique in that it is the first described in this location. The tumor appears homogeneous and intensely enhanced after IV on CT, and hypointense on MRI on both T1- and T2-weighted images.

Prevention of adverse reactions to intravascular contrast media.

The exact mechanisms of adverse reactions to contrast media are still imperfectly known; they may, however, be idiosyncratic or non-idiosyncratic. Non-idiosyncratic reactions can be prevented by using new non-ionic contrast agents. Idiosyncratic reactions can be prevented by specific premedication.

[Unresectable hepatic adenomas. Management by selective hepatic artery embolization].

Four patients with unresectable hepatic adenoma underwent selective hepatic artery embolization. Non-operability was related to the size and the situation of the tumor, and the clinical background. The only subsequent postembolization syndrome was one case of acute renal failure, reversible after diuretic treatment.

Transalar sphenoidal encephalocele. Uncommon clinical and radiological findings.

A case of basal encephalocele protruding through a defect in the greater wing of the sphenoid bone is presented. The transalar type of encephalocele is uncommon and unclassified. This case, documented by computed tomography and magnetic resonance imaging, is unique in that it presented with trigeminal neuralgia and was associated with an angioma of the soft palate.

[Percutaneous transluminal angioplasty of portosystemic shunts].

Percutaneous transluminal angioplasty was performed in 3 patients with stenotic portosystemic shunt (one splenorenal, one mesocaval, and one arterialized splenoportal shunt). In the first two cases, the procedure was successful, followed immediately by widening of the shunt and a decrease of the splenorenal and mesocaval pressure gradient. Shunt patency was confirmed at long term as the patients showed no evidence of esophageal varices or recurrent variceal bleeding.

[Imaging of cancer of the uterine cervix].

Recently, magnetic resonance imaging (MRI) and transrectal or transvaginal ultrasound (TRUS, TVUS) had an important place in imaging techniques of cervical carcinomas and raise the question of modifying the imaging strategies. For the diagnosis of primitive tumor, those techniques cannot take the place of clinical examination and gross examination. In the assessment of parametrial involvement, TRUS which has better accuracy than clinical examination, and MRI which is considered as the most accurate technique, have an important role to play.
